Abstract

Funciones de ruido de confort monitorean el ruido de fondo captado por los microfonos de los sistemas de radiocomunicaciones. Estas funciones proporcionaninformacion de ruido de confort que es transmitida por las unidades remotas durante losperíodos de silencio, de modo que el equipamiento de la parte receptorapuede dar salida a sonido de fondo apropiado, mientras el lado de la transmision puede desactivar los circuitos de transmision para ahorrar energía. Lasfunciones deenmudecimiento se ada ptan mediante el suministro continuo de senales a funciones de ruido de confort de modo que el ruido de fondo se monitoreaconstantemente. Cuando se activa el modo de enmudecimiento de una unidad remota, el transmisor recibe lastramas de ruido de con fort o las tramas de silencioen lugar de la salida de informacion del codificador de voz (habla).
